The presidents aren't kings. They need congressional support to get anything major done. They rarely support sweeping changes.

And more recently, congress essentially won't do anything, period. Either because the president is not of their party, or more recently, chaos within the Republican party itself.

Which is why you see presidents trying to do things with executive orders, but typically the courts (correctly) block overreach there. Trump is busy accumulating court rulings against his administration.
